When the engine Nitro of your radio-controlled car won't start it can be very frustrating. All too often, we tend to immediately attribute the problem to a fault in the engine, when in fact it only takes a few checks to find the root cause. We hope this guide will help you to get your car Nitro back in working order.
Check the fuel
Fuel too old?
A nitro-old fuel deteriorates as it absorbs moisture, which can lead to erratic or non-existent engine operation. Try using fresh fuel.
Really old fuel can also become sticky and clog fuel and carburetor tubes. If this happens, you can clean your fuel tankfuel tank, hoses and carburetor with a cleaning product engine/carburator cleaner. Fuel hoses can be replaced with new ones.
Store nitro-
Keep your fuel containers tightly closed to prevent moisture from entering. Do not store in direct sunlight. car this can degrade the fuel (and fuel is flammable). When refueling, minimize the time the fuel container is open for the fuel to enter. keep it cool for as long as possible.
Look for leaks
The first thing to do before you try again is to check for leaks. start your car again Nitro is to quickly check that it's in good working order.
Make sure that all fuel tubes are correctly connected in accordance with the manual, and that there are no cuts or cracks. Check that the fuel tank cap is tightly closed and that there are no cracks or fissures in the tank. Check that the seals resonator do not leak.
Check spark plugs
Is your glow plug heater working?
Make sure your candle warmer is fully charged and working. Test it on a spare spark plug. If the glow plug heater works correctly, the candle should start to glow.
Are your candles defective?
One of the most common reasons for an engine's Nitro engine won't start is faulty spark plugs. Once you are satisfied with the operation of the spark plug heater, check the spark plug installed in the engine. nitro. To do this, remove the glow plug with a wrench and hold it to your glow plug heater. If it doesn't light and you're sure the glow plug heater is charged and working, it's either burnt out or faulty. Find a new spark plugMake sure it glows and install it in the engine.
Prime your engine and try to start it.
We now know that the problem is not a faulty or burnt-out glow plug, and that the glow plug heater is working. The engine is not seized and has good compression (some resistance when you try to start it). You've repaired any air leaks you found. After a good check, the next step is to try to start the engine.
For prime your engineplace your finger or a cloth over the exhaust pipe and pull the pull starter (or start the engine with your starting bench or roto start) several times until you see the fuel being drawn through the hose into the carburettor. At first, there will probably be some air bubbles in the line, so keep priming until there are none. Some engines have a priming button on the fuel tank; you can press it to obtain the same result.
Note If you can't get fuel to flow through the hoses, there's probably a blockage in the tank, hoses or carburettor. This is often caused by dirt or debris. If the car has been parked for a long time, old fuel can become sticky and thicken, also causing blockages.
Once the engine is primed, try to start it. With a bit of luck, after several attempts, it should light up.
Your engine still won't start
Is the engine flooded?
If you have flooded the motor (meaning that there is too much fuel in the engine due to a over-priming for example), it will be very difficult to start the engine. To solve this problem, you'll need to remove the glow plug and then turn the engine over, pulling the glow plug several times. remove excess fuel. Replace the glow plug and try starting the engine again.
Is the carburetor properly adjusted?
If your engine still won't start, try adjusting the carburettor settings. It may be that not enough fuel is passing through, or too much! If you wish to increase fuel flowIf you wish to increase fuel flow, enrich the engine by turning the screw to the left. decrease fuel flowIf you wish to decrease fuel flow, turn the screw to the right to deplete the engine. When the engine smokes a lot and doesn't warm up, the setting is too richIf it smokes a little and rises too much, the setting is too lean.
